2 Claims.

This invention relates in general to broilers for fluid fuel burning stoves, and has more particular reference to mechanism therein for adjustably varying the distance between the broiler pan and/or the product being cooked and the flame.

Mechanism for such purpose has heretofore been provided, as disclosed in U. S. Letters Patent No, 1,861,689 issued June 7, 1932, but in such prior art devices access to the product being cooked has been had only by withdrawal of the drawer, while still having the actuating means for the pan height adjusting mechanism extend through the front end of the drawer.

A principal object of the present invention is the provision of raising and lowering means for the broiler pan, having actuating or control means therefor extending outwardly through a closure member for the broiler oven, which closure member may be opened without alecting the pan raising and lowering means to give access to the product being cooked without removing the latter from the oven.

Another important object of the invention is the provision in such a broiler of a hinged closure member having novel counterbalancing and movement limiting means, and carrying mechanism for controlling the vertical height of the broiler pan when the member is in closed position.

A further important object of the invention is the provision in such a broiler of mechanism for raising and lowering the pan in any adjusted position even when the control mechanism for said actuating mechanism is disconnected therefrom.

A still furtherobject of the invention is the provision of a single member for opening and closing the broiler oven door, and the drawer (if one be provided), and also for operating the broiler pan raising and lowering mechanism.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

In the drawings,

Figure 1 is a transverse section through a broiler embodying the features of .my invention, 50 with the drawer shown in partially withdrawn position and the door therefor opened, in dotted lines;

Fig. 2 is a front elevation of the broiler pan and actuating mechanism therefor, parts being shown in section;

Fig. 6 is a detail sectional View taken substantially on the line 6 6 of Fig. 4; and

Fig. 7 is a detail vertical section taken sub- 10 stantially on the line 1 1 of Fig. 2.

For the purpose of illustrating my invention, I have shown in the drawings a broiler comparty ment or oven, of any desired or well-known construction, indicated generally at I I, which is or 15 may be supported on a suitable frame I2, and a drawer I3 adapted to be moved into and out of said compartment. A door or closure member I4 is hingedly secured to this drawer in a manner to be later described, and is adapted to t snugly within a suitable flanged opening inthe front wall I5 of the compartment or oven II. It will be readily apparent that the door I4 may be hinged to the front wall I5 and the drawer per se entirely eliminated by securing the broiler pan raising and lowering mechanism within the oven II, if such an. arrangement is desired.

The drawer I3 comprises a skeleton frame made up of a front member I6, preferably of cast;r

respectively, rigidly secured in any suitable man- 30 ner to each other, said side and rear members being preferably stamped from suitable gauge sheet metal.

Rollers 2I may be rotatably mounted upon 35 rearward extensions of the rear frame I9 for engagement in suitable trackways provided at the sides of the compartment II, and rollers 22 may .be provided within the compartment to cooperate with the side frame members II and I8 to 40 support the drawer I3 in its movements in and out of the compartment.

Two parallel rods 23 and 24, the ends of which are rotatably supported in any desired manner in the front and rear frame members I6 and respectively, constitute part of the broiler pan raising and lowering mechanism. Each rod 23,

24 is provided adjacent each end with an arm 25 rigidly secured thereto in any suitable manner, and the rearward pair of arms and forward pair of arms are pivotally connected by means of pins 26 with links 2'I, respectively, at their upper ends.

A pan supporting member 28 is slidably mounted between each of the links 21 and the levers or 55 iron, and side and rear members I 1, I8 and I9,

arms 25 by means of a pair 0f elongated slots 29 therein co-operating with the pins 26. Supported on the two members 28 is a broiler pan 3| of any desired construction which may be provided with depending marginal flanges 32 at the front and rear ends thereof, having a notch or cut-away portion 33 which is adapted to flt over the outer end of a pin 34, the inner end of which is rigidly secured to the supporting member 23, whereby the pan 3| is prevented from sliding longitudinally relative to the supporting members 28.

Rotatably mounted on each of the pins 34 is one end of a compensating link 35, the other end of each of said links being pivoted at 36 to the right-hand front and rear arm 25, respectively. The links 35 are dimensioned and located to hold -the movement ofthe pan supporting members 28 Y to a straight vertical line in the raising and lowering thereof through the operation of the parallel motion mechanism comprising the members 23, 24, 25, 26, and 21, the pins 26 sliding in the slots 29 in such movement. A spring 31, secured at one end to the rear pivot pin 36 and at the other end to a suitable stud pin 38 rigidly secured to the rear frame member I9, may be provided to aid in counterbalancing the weight of the pan 3|, its associated mechanism, and the product being cooked.

In order to actuate the above described broiler pan raising and lowering mechanism, a segmental bevel gear 39 is rigidly secured to the forward end of the rod 24A immediately in front of the frame member I6, and is adapted to co-operate with and be actuated by a complementally beveled pinion 4| rigidly secured 'to the inner end of a shaft 42 which is rotatably mounted in the door |4 and has rigidly secured'to its outer end a suitable handle 43. The pinion 4I and segment 39 are so beveled to facilitatetheir meshing 'together when therdoor I4 is swung from open to closed position. The door I4, which is of the usual hollow construction, may be provided with a semicircular depression or recessed portion 4'4 within which the pinion 4| may be housed and which is adapted to receive the segment 39 when the door is in closed position.

The segment 39 is vso proportioned and positioned, as will be seen in Figs. 2 and 3, that it is substantially statically balanced relative tothe rod 24 when the broiler pan is in its lowermost position. As the pinion 4| is actuated to rotate the segment 39 in a counter-clockwise direction to raise the `broiler pan by means of the abovedescribed parallel motion linkage, the center of gravity of the segment 39 will be carried to the left of the ro'd 24 so that the weight of said segment will aid in counterbalancin'g the weight of the linkage, the broiler pan, and the product `to be cooked. By means of this 'arrangement and the spring 31 the pan 3| will Ybe maintained in any adjusted position even when the pinion 4| is disengaged from the segment 39 when the door I4 is opened.

A stop member or lug 45 is formed integral with the front frame rmember I6 so as'to be contacted by the left-hand front arm 25 to limit Ythe down- Ward movement of the pan 3|, as seen -in Figs. 3 and 4, and the upward movement thereof will be limited by the pins 26 contacting the left-hand end of the slots 29 (Fig. 2).

Rigidly secured to the front frame member I6,

Vopened position,

by screws 46, are two hinge plates 41l which, with complemented hinge plates 48 which are secured in any desired manner to the lower part of the door |4, embrace the usual hinge pin 49 to pivotally support said door or closure member.

Suitably secured to the inner wall of the door I4 adjacent the hinges therefor are two pairs of brackets 5| (Figs. 1, 4 and 5), each of which supports a pin or stud 52 upon which is pivotally mounted one end of a lever or stop member 53. The other end of each of the levers 53 is secured to one end of a coil spring 54 which is anchored at its other end to a suitable stud 55 secured to the side frame members I1 and I8, respectively. Intermediate their ends the levers 53 are each provided with a notch 56 forming a vertical shoulder at the back side thereof which is adapted to abut against a lug 51 formed integral with the front frame member I6 when the door I4 is completely open to limit its downward pivotal movement.

The springs 54 function as counterbalancing means for the door I4 as well as tending to close the same when it is in partially open position, and normally maintaining it in closed position. As can be seen from Fig. 5, due to the arrangement of the members 53 'and 51 relative to the hinge of the door when thelatter is in fully a toggle-like effect is attained whereinthesprings 54 tend'to maintain the door in such fully openedposition. y

'It will be apparent that the above described mechanism constitutes a broiler structure in which the closure member may be opened to give access tothe product `to be 'cooked without removing the latter from the oven compartment while still permitting vertical adjustment of the broiler pan from the exterior of the compartment when the closure member is closed.

'It is thoughtthat the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without-departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
